GANG-PLOW.

Specification of Letters Patent.

Application filed December 8, 1916. Serial No. 135,807.

Ib all whom t may concern.'

Be it known that I, RHIN'EHART V. KUEN, a citizen of the United States,residing near Amana, in the county of Iowa and State ot Iowa, haveinvented VCertain new and useful Improvements in Gang-Flows; and I. dohereby declare the following to be a tall, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

rIhis invention relates to sulky gang plows, the object of the inventionbeing to provide a simple automatic device to support the plows inraised position, and also adapted to be used to force the plows into theground.

The invention is fully disclosed in the accompanying drawing, anddescribed and claimed in the specification following.

In the drawing, forming a part olf this specification, Figure 1 is afragmentary view of a typical gang-plow in perspective, with my improvedlocking device attached, the plow being depressed. Fig. 2 is a similarview, showing the position of the parts, with the plow elevated.l Fig. 3is a front elevation oi the same.

In the drawing, the numeral 1 denotes the sulky wheel which runs on theunplowed land, mounted on a cranked aXle 2, which may be partiallyrevolved to give proper adjustment to the wheel by a hand-lever notshown. On the axle is mounted the main frame 3, which carries thedrivers seat not herein shown, but supposed to be at the left of Fig. 1.On the aXle is also mounted revolubly a tubular member 4 provided with aforwardly projecting arm 5, to which is pivotally bolted a link 6connecting with the plow-beam 7 by a bolt or stud 8. Extending in anopposite direction is a toot-lever 9, reached by the driver as heoccupies his seat, and by means oi which the plow may be elevated, aswill be seen by a comparison oi Figs. 1 and 2. In the ordinary gang-plowthere is also provided a strong spring 10, connecting with the same studor bolt at one end, and to the machine frame or some of its connectionsnear the rear, the connection not being herein shown, as it and all ofthe parts above described are of familiar construction, and form no partof this invention.

It may be further explained that in gangplows as commonly built theplows are sup-V ported in elevated position by a 'dog or lever and anotched sector or the like. In time the dog or notches become worn so`much that they will not hold, and there is then no way to support theplows except by continuous pressure on the foot-lever.

eferring now to Fig. 1 it will be seen that a link 11 is pivoted to thearm 5 by aV bolt 12, some distance back from the connection of the link6 therewith. To the other end oi this link is pivoted a somewhat longerlink 13, as by a bo-lt 14, the upper end of 'the longer link'beingpreferably folded back upon itself at 15 to receive the end of the shortlink, and somewhat extended upwardly, for a purpose which will beexplained presently. The lower end ol the long link connects with thebolt or stud 8. Near this pivot is hooked tho spring l0, which tends topull the link backwardly, as will be evident. Near the middle the longlink is curved, so that when shifted to the position shown in Fig. 2 thepivots 8, 12 and are practically in line, the curve of the long linkabutting against 12, where it is held by the tension of the spring.rlhis, as will be evident serves to lock the parts, and the plows arethus held in suspended position.

To trip this locking toggle lever, and thus permit the plows to descend,I provide a foot-lever 1G, which is preferably stirrupshaped, and hungon the pivot 12. An eX- tension 17 of the lower end is adapted to engagethe under side of the tubular rockshai't e', and thus support thetoot-lever stirrup when theplows are depressed. When in this position,shown in Fig. 1, it is also evidentthat pressure on the stirrup willserve to force the plows downwardly, provided, 'of course, that they arenot held in a fixed position' by other means. Crossing the stirrup is across-bar 18, which engages the extended upper end of the link 13 whenit is desired to trip thc toggle from its plowsuspending position. Itwill be understood that in the operation of the device this crossbarneve-r passes in front oli' the upper end oi the long link.

Referring to Fig. 3 it will be seen that the long link 13 is preferablyoffset at 19, so as never to `foul with the short link.

rllhe operation of the device, which has already been indicated, is verysimple. To elevate the plows, depress the foot-lever 9 (or use any otherlever that may be provided' tor that par the operator has only to pose-)This action causes all the parts to rise and automatically assume theposition shown in Fig. 2 if the foot-lever be far enough depressed. rlheelevated plows are new in locked position. rllo unlock them and allowthem to descend the operator has only to push the stirrup-lever forward,tripping the locked toggle. rlhis lever will be referred to hereafter aSthe trip-lever.

rlhe nature of the device is such as not t0 be injuriously affected byordinary wea-r, or to get out of order, and affords the operator asimple and easily operated means for controlling the positions of theplows, as above set forth.

Having thus claim:

l. In a gang-plow, the combination with the plow-beam lifting apparatus,comprising a lift-lever, an arm cooperating therewith and a linkconnecting said arin with the plow-beam, of a supporting device,consisting of a toggle, one extremity of which connects pivotally withthe plow-beam, and the other with said arm, some distance from theconnection of the supporting link therewith, the toggle being adapted tofold back on itself and lock when the plow is fully elevated.

2. Combined with the lifting arm of a gang-plow, a connecting link and aplowbeam attached thereto, a toggle consisting of a long and short linkconnecting the plow-beam and said arm at some distance described myinvention, I

Gopes of this patent may be obtained for five cents each, by addressingthe from the supporting-link connection, and a spring attached to one ofthe toggle-links to hold it when folded back upon itself and in lockedposition.

3. Combined with the lifting` arin of a gang-plow, a connectedsuspending link and a plow-beam attached thereto, of a toggle attachedat one of its extremities to the plow-beam and at the other to said armsome distance from the connection of the suspending link, and foldingback on itself to locked position when the plow is elevated, and atrip-lever adapted to engage said toggle and disengage it from thelocked position.

4t. Combined with the lifting arm of a gang-plow, an attached link and aconnecting plow-beam, of a toggle connecting at one extremity to saidbeam and at the other to said arm at some distance from the connectionof the suspending link, and folding back to locking position when thebeam is elevated, and a swinging trip-lever adapted to trip the lockedtoggle to release the suspended beam, and when the suspending arm isdepressed to engage it rigidly, whereby said trip-lever may serve toforce the plows into the ground. p In testimony whereof l ai'ix mysignature in presence of two witnesses.
